Road and traffic signs and road construction signs provide guidance for navigating roadways and parking lots. They are very helpful to call attention to hazards, regulate traffic and provide information to help prevent accidents. The R9-11a Sidewalk Closed Cross Here signs should be used where pedestrian flow is restricted and installed just beyond the point to which pedestrians are being redirected. At areas of construction near or on the sidewalk, the R9-11a Sidewalk Closed Cross Here sign should be installed at the beginning of the closed sidewalk or at the intersections preceding the closed sidewalk to help pedestrians navigate around the restricted area. Additional signage may be needed to help safely guide pedestrians around the closed sidewalk section.
